Which property of physical changes explains why matter is conserved in a physical change? The arrangements of particles do not change, and the bonds between atoms do not break. Mass, not energy changes in a physical change.
Energy and mass change in a physical change.
The bonds between atoms do not break, it's only the arrangement that changes.

Mass is the amount of matter in an object, and weight is the downward pull on an object due to gravity. Which property of physical changes explains why matter is conserved in a physical change? The bonds between atoms do not break; it is only the arrangement that changes.

hope I helped! :)

the ratio of the conjugate base to the acid required to attain the desired ph.
